PDI Vacuum Piston for Tokyo Marui VSR-10

Description

Using a specially patented design, the Vacuum VC system allows air to enter the cylinder cavity when you cock the rifle, which allows for easier cocking motion. Once the rifle is fired and the piston is sent forward, its unidirectional vent is closed to ensure maximum power transfer.
